For better or for worse, and any system never has to be set in stone for ever [as Belgium showed against Japan] , but Southgate is picking up where Hoddle left off - that is, looking to keep the ball, playing out from the back through the midfield and using wing backs as offensive options.
People have got short memories - England had years of bypassing the midfield, hoofing the ball forward, sending the target men on wild goose chases and basically achieving very little other than giving the ball back to the opposition. It was dour, predictable and got the team nowhere. And we had years of it.
It's obviously not as clear cut as that, it's not a case of we only play 'this way' and never 'that way'...but the idea, just the basic notion of looking to keep the ball and building pressure is not such a bad place to start instilling an idea of how you want the team to play.
